Abstract (en)
[origin: EP1887027A1] Resin particles which are excellent in electrostatic property, thermal storage stability and thermal properties, and have evenness of particle diameter are to be provided. The resin particles are core-shell resin particles (C2) each comprising one or more film-like shell layers (P) comprising a first resin (a) and a core layer (Q) comprising a second resin (b). Core-shell type resin particles (C2) each comprising a film-like shell layer (P) in one or more layer structure comprising a first resin (a) and a core layer (Q) in one layer structure comprising a second resin (b), wherein the weight ratio of (P) and (Q) is in a range of (0.1:99.9) to (70:30), the content of volatile components of (C2) is 2% by weight or lower, and (a) has an initial softening temperature of 40 to 270°C, a glass transition temperature of 20 to 250°C, a flow temperature of 60 to 300°C, and the difference of the glass transition temperature and the flow temperature in a range of 0 to 120°C and contains 20 to 80% by weight of vinyl acetate as constituent units.
